摘要: 振动压路机在振动压实过程中,振动轮和土体之间存在复杂的动态相互作用。在ABAQUS中建立了振动压 路机的振动轮-土体有限元模型,对振动压实过程进行了仿真分析。结果表明:振动轮-土体有限元模型可以很 好地仿真振动压实过程的非线性响应,为振动压路机的设计和压实效果的预测奠定理论基础。

关键词: 非线性有限元, 振动压实, 仿真分析

Abstract: There are complex dynamic interactions between vibration wheel and soil in the process of vibrating compaction. In this paper, a finite element m ode l o f the vibration wheel and soil in ABAQUS w as established; vibration compaction process was analyzed; the results demonstrated that finite element model could be a good simulation o f the non linear response of the vibrating compaction process, which could help design and predict vibratory roller compaction effect.

Key words: non linear finite element, vibration compaction, simulation
